If you have been researching infrared sauna therapy, you have probably seen three terms: near, mid, and far infrared. They all use infrared light, but the wavelengths are different, and so is the way they interact with the body.
Not every sauna offers full spectrum infrared or third-party tested emissivity, which is why the quality of the technology matters.
Here is a simple breakdown of what each one does, and why Wellnest uses the Sunlighten mPulse full spectrum infrared sauna, which offers all three wavelengths through personalized programs in one session.
What Is an Infrared Sauna?

An infrared sauna uses infrared light to heat the body directly, instead of only heating the air around you like a traditional sauna. This creates a gentler heat experience while still encouraging sweating, circulation, and deep relaxation.
Infrared light sits on the electromagnetic spectrum and is divided into three therapeutic bands:
- Near infrared, 700 to 1,400 nm
- Mid infrared, 1,400 to 3,000 nm
- Far infrared, 3,000 nm to 1 mm
Each wavelength supports the body in a different way.
How Is Infrared Different from a Traditional Sauna?
A traditional sauna heats the room first, creating very hot air that can feel intense or harder to tolerate for some people.
An infrared sauna works differently. The infrared wavelengths are absorbed by the body, helping raise core temperature from within. This is why many people find infrared sauna sessions easier to tolerate, while still getting the benefits of heat, sweat, and recovery.
Near Infrared Sauna Benefits
Near infrared is the shortest infrared wavelength. It is often linked with skin health, cellular repair, and photobiomodulation, which means light energy interacting with the cells.
Near infrared supports:
- Skin renewal
- Collagen production
- Cellular energy
- Surface-level recovery
- Healthy inflammatory response
This wavelength is often chosen for skin-focused and cellular wellness goals.
Mid Infrared: The Bridge Wavelength
Mid infrared sits between near and far infrared. It is commonly used for circulation, muscle recovery, and targeted relief from tension.
Mid infrared supports:
- Muscle relaxation
- Recovery after training
- Joint stiffness
- Circulation
- Pain relief support
For active bodies, desk-dominant routines, and people who feel tight or overworked, mid infrared can be a helpful part of a recovery routine.
Far Infrared Sauna Benefits
Far infrared is the most commonly researched infrared wavelength in sauna therapy. It is known for creating a deep warming effect that supports sweating, circulation, and whole-body relaxation.
Far infrared supports:
- Natural detoxification through sweat
- Cardiovascular wellness
- Muscle recovery
- Stress relief
- Better sleep
- Deep relaxation
Research on far infrared sauna and repeated thermal therapy has shown benefits for quality of life, immunity, chronic pain, fatigue, and cardiovascular function. While an infrared sauna is not a medical treatment or replacement for care, it can be a supportive longevity tool when used safely and consistently.
What Is a Full Spectrum Infrared Sauna?
A full spectrum infrared sauna uses near, mid, and far infrared wavelengths together at different intensities. This allows the body to receive a wider range of infrared benefits in one session.
At Wellnest, our Sunlighten mPulse sauna offers red light, near infrared, mid infrared, and far infrared through targeted wellness programs. Sunlighten’s mPulse technology separates the wavelengths based on each program’s goal, allowing the session to be more precise and personalized.
The sauna also uses SoloCarbon heater technology, tested to deliver up to 99% emissivity. Emissivity refers to how efficiently infrared energy is emitted, which is an important marker of sauna performance and infrared quality.
At Wellnest, the infrared sauna programs include:
- Detoxification: Mid and far infrared, high to low intensity, 37 minutes
- Pain Relief: Near, mid, and far infrared, medium constant intensity, 30 minutes
- Relaxation: Near, mid, and far infrared, gentle low intensity, 40 minutes
- Cardio: Near, mid, and far infrared, high to medium intensity, 45 minutes
- Anti-Aging: Near, mid, and far infrared, low intensity, 30 minutes
- Weight Loss: Mid and far infrared, high to medium intensity, 30 minutes
This makes the infrared sauna more than a heat session. It becomes a biohacking tool for recovery, cellular health, and longevity-focused wellness.
Frequently Asked Questions
What is the difference between near, mid, and far infrared saunas?
The difference between near, mid, and far infrared saunas is the wavelength depth and how each one interacts with the body.
Near infrared supports skin health and cellular energy, mid infrared supports circulation and muscle recovery, and far infrared penetrates the deepest, helping raise core temperature for deep sweating, relaxation, and detoxification.
Is infrared sauna good for muscle recovery or pain relief?
Yes, infrared sauna sessions can support muscle recovery and pain relief by raising the body’s core temperature, improving circulation, and encouraging heat-based relaxation in tight or overworked muscles.
As the body warms, blood vessels widen and circulation increases, helping deliver more oxygen and nutrients to the muscles. Heat exposure may also activate heat shock proteins, which are involved in cellular repair, stress protection, and recovery. For this reason, infrared sauna can be a supportive tool for post-workout recovery, muscle stiffness, joint discomfort, and general body tension.
However, recurring pain should always be assessed by a specialized practitioner to help identify the source of discomfort and create a lasting pain management plan.
Is an infrared sauna the same as a traditional sauna or steam room?
No. A traditional sauna heats the air around you with dry heat, while a steam room uses moist heat and high humidity to stimulate sweat.
An infrared sauna works differently. It uses infrared light to warm the body more directly through radiant heat, helping raise core temperature without relying on extremely hot air.
Many people find infrared heat gentler and easier to stay in than the intense heat of a traditional sauna or steam room.
How much does an infrared sauna session cost in Dubai?
At Wellnest, an infrared sauna session is AED 150, with package options available for those who want to include sauna regularly in their wellness routine.
Across Dubai, pricing can vary depending on the sauna type, session duration, technology, and package structure.
Can an infrared sauna help with weight loss?
Infrared saunas can support weight loss goals by raising the body’s core temperature and increasing heart rate during the session, similar to the way the body responds during low to moderate cardio.
It also encourages sweating and supports circulation, which can help reduce water retention and leave the body feeling lighter.
However, infrared sauna does not replace movement, nutrition, or a consistent wellness routine. It is best used as a supportive biohacking tool alongside healthy lifestyle habits.
